WATCH. l

Specification of Letters Patent.

Patented Apr. 18, 1916.

Application led J'uly 24, 1915. Serial No. 41,749.

To all whom it may concern Be it known that we, JOSEPH RosEMoNT andFRAM; AMATI. subjects of the King of Italy, residing at Trenton, in thecounty of Mercer and State of New Jersey, have invented new and usefulImprovements in `Watches, of which the following is a speciiication. g

This invention relates to certain novel and useful improvements inwatches.

In carrying out the present invention it is our purpose to provide awatch wherein the dial may be illuminated conveniently whenevernecessary or desired in order to facilitate the reading thereof.

It is also our purpose to provide a watch wherein the lamp, source ofenergy therefor, and switch controlling the connection between thesource of energy and the lamp will be carried by the watch so arrangedas to produce a neat and compact article and one wherein the possibilityof derangement of component parts will be reduced to a minimum.

With the above recited objects in view and others of a similar nature,the invention consists in the construction, combination, and arrangementof parts set forth in and falling within the scope of the appendedclaims.

In the accompanying drawing: Figure 1 is a face view of a hunting casewatch constructed in accordance with the present invention. Fig. 2 is asectional view through the watch. Fig. 3 is a sectional view. Fig. 4 isa fragmentary sectional view through the watch of the open face typeconstructed in accordance with our invention.

In accordance with our invention, the case of the watch is slightlyincreased in diameter and a channel formed therein concentrically of thegear train and disposed within this channel is a battery, while mountedupon the dial of the watch is a lamp and a switch connected in seriescircuit with the battery. This switch is under the control of the stemof the watch and when the stem is moved inwardly, the switch is closedso that current may fiow from the battery through the lamp to energizethe latter and illuminate the dial, thereby enabling the dial to be readeasily7 and conveniently under all conditions.

Referring now to the drawing in detail, 1 designates a watch of thehunting case type. The case of the watch is slightly increased indiameter .to form an annular chamber or channel 2 arrangedconcentrically of the case and around the gear train. Disposed, withinthe chamber 2 are dry cells 3, 3 each curved longitudinally to conformto .the channel. Suitably secured to the partition between the geartrain and the dial of the watch is an electric lamp receptacle 4carrying a lamp 5 disposed within an opening formed in the dial andadapted to illuminate the dial when energized. Also secured tothedivision plate carrying the socket or receptacle 4 is a switch 6. In thepresent instance this switch embodies a base 7 o f fiber or otherinsulating material, a stationary contact 8 secured to the base, and amovable contact finger 9 secured to the base and composed of springymaterial. This movable contact is normally spaced apart from thestationary contact and is disposed in the path of movement of a pin 10slidably mounted within an opening l1 formed in the flange carrying thedial. Secured to the pin 10 at the inner side of the flange that carriesthe dial, is a stop nut 12 while fastened to the outer end of the pinbeyond said flange is a collar 13 and interposed between the collar 13and the flange is a coiled expansion spring 14 acting to hold the innerend of the pin normally out of engagement with the spring contact finger9. In this form of our invention, a disk 15 is fixed to the stem of thewatch concentrically of said stem in juxtaposition to the outer end ofthe pin 10. The battery formed of the cells 3, the lamp and the switchare connected in series circuit as clearly illustrated in Fig. 2 of thedrawing.

In practice, when it is desired to energize the lamp so as to illuminatethe dial, the stem of the watch is forced inwardly and as the stem nearsthe limit of its inward movement the disk 15 engages the pin 10 andslides the latter against the tension of the spring 14, and in thismovement of the pin, the inner end thereof engages the spring contactfinger 9 and moves such finger into engagement with the stationarycontact thereby closing the circuit and energizing the lamp.

llhen our invention is installed in a hunting case watch, the stem ispreferably capable of sliding movement relatively to the crown, as shownin Figs. 1, 2 and 3 of the drawing, and the disk 15 is so arranged rela-`tively .t0 .the outer end of the pin 10, that in the initial movementof the stem, the cover will be released, while the pin will re* mainuninfluenced by the disk. In the continued movement of the stem,succeeding the release of the cover, the crown moves inwardly with thestem and the disk engages the pin to close the switch.

In the construction illustrated in Fig. 4, we have shown the stem andcrown fixed to each other and this construction is preferably used inopen face watches.

Having vdescribed our invention, what is claimed is:

1. A watch including a stem, a dial, a gear train, a plate, and a flangefor holding the dial and having the case formed with an annular chambersurrounding the gear train, a battery in said chamber, a lamp carried bythe plate between the gear train and the dial and projecting through thedial, a switch on said plate, a pin slidably mounted within the liangecarrying the dial oi' the Watch, a disk on the stem of the Watch andmovable therewithpto engage said pin to move ythe latter into engagementwith the switch to close the same, and circuit connections between saidbttery, lamp, and switch. 2. A watch including a stem, a dial, a geartrain, a plate, and av flange for hold'ing the dial and having the caseformed with an annular chamber surrounding the gear train, a battery insaid chamber, a lamp carried by the plate between the gear train and thedial and projecting through the dial, a switch on said plate, a pinslidably mounted within the flange carrying the dial of the watch, adisk onthe stem of the watch and movable therewith to engage said pin tomove the latter into engagement with the switch to close the same,circuit connections between said battery, lamp, and switch, and a springholding said pin normally out oit engagement with said switch. i -Intestimony whereof we affix our signatures in presence of a witness.
